My problem with e-book readers is let's say I buy a book and it's good. Now, in the past, if I had a book that I read, liked, and I have a friend who may like it, I lent them the book for them to read and either keep (ie lend to someone else) or give back to me depending on the book. With textbooks, it was called selling them back to the bookstore. With DRM, etc., how am I to do that? Also, say I don't have DRM on the ebook. How do I get them the file? Do they bring their kindle/whatnot over, I connect it to my computer and transfer the ebook file? Do I email it to them? Send it over a file server? Give it to them on a jumpdrive? See, with sharing a physical book, it's a matter of getting together and handing them the book, which takes no real time, since it's an opportunity to be social with the person I'm lending the book to and presumably like as a person.
